A witness is a person who gives testimony or provides relevant information in a legal proceeding. In plain language, it is someone who helps prove facts because they observed events, know important details, or have specialized knowledge.
Why It Matters
The term matters because witness testimony often drives the narrative of a case. Courts and juries frequently need to decide not just what a witness said, but whether the witness was credible, qualified, biased, or mistaken.
Where It Appears
The term appears in trials, hearings, depositions, affidavits, investigations, criminal cases, civil litigation, and administrative proceedings.
Practical Example
A bystander who saw a collision, a company employee who handled a contract, and a doctor explaining an injury may each appear as witnesses for different reasons.
